3.3 BMS Protections
For all BMS protection and recovery values, refer to Section 3.2 above.
Over Charge Protection
During charging, if the voltage of any cell exceeds the setting for cell protection or
the total voltage of the system is greater than the Max Charging Voltage, the BMS
stops charging. When the voltage of each cell and the total voltage of the battery
drops to the recovery values, the protection is removed.
Over Discharge Protection
During discharge, if the voltage of any cell or the total voltage of the battery is lower
than the protection values, the BMS stops discharging. When all cell voltages and the
total voltage reach the recovery values, the protection is removed.
Charging Over Current Protection
During charging, if the current surpasses the protection value, the BMS will limit the
charging current to less than the protection value.
Discharging Over Current Protection
During discharging, if the current surpasses the protection value, the BMS stops
discharging. Remove the load or charge the battery to remove the protection.
Short Circuit Protection
During discharging, if the current is so much bigger than the normal working current,
it’s considered a short circuit, the BMS will stop discharging.
Reverse Polarity Protection
When the battery and rectifier are in reverse connection, the BMS will immediately
enter a state of polarity protection to protect the battery and rectifier from being
damaged by high currents.

Cell Temperature Protection
If the temperature of any cell surpasses 70°C or drops below 0°C, the BMS will stop
charging. If the temperature of any cell surpasses 75°C or drops below -20°C, the
BMS will stop the discharge.
PCB High Temperature Protection
If the PCB temperature surpasses 95 °C, the BMS will stop charging or discharging
until the temperature drops below the recovery value.
Cell Balancing
During charging, if all cell voltages are greater than 3.4V and the voltage difference
between cells (ΔU) is > 40mV (ΔU = Max. Cell Voltage - Min. Cell Voltage), the BMS
will trigger the balancing process.
3.4 Control Panel Indicators
BMS Protection Indicators
When the LED alarm light comes on, a BMS protection has been triggered and the
battery has been protected. Please refer to the table below for individual warning
indicators and their recovery process and take the appropriate action.
